Irgastab® IS 3026 L

Technical Datasheet | Supplied by BASF
Irgastab® IS 3026 L by BASF is a 40% active aqueous micro-emulsion, containing a thermal stabilizer package for vinyl polymers. It protects the substrates against thermal degradation of polyvinyl chloride (PVC) during manufacturing, processing and end use. It is uniformly dispersed in the reaction mixture, the resulting PVC develops improved qualities, such as excellent heat stability and low color. Irgastab® IS 3026 L imparts good chain terminating properties during PVC polymerization. It can be recommended at concentration levels of about 0.03–0.08% as chain stopper & thermal stabilizer for the PVC polymerization.
